I wonder what the practical reasons for starting with h.264 are.

I found the article to be rather confusing.
One thing to point out is that the video codec used in this research (but for which results weren’t published for some reason), H264, is not at all state of the art.
H265 is far newer and they are already working in H266. There are also other much higher quality codecs such as AV1. For what it’s worth, they do reference H265, but I don’t have access to the source research paper so it’s difficult to say what they are comparing against.
The performance relative to FLAC is interesting though.

Low/no patent issues, much simpler complexity

Vvc is h266, the spec is ready it’s just not in a lot of hardware, or even decent software yet, that often takes a few years.
Av1 isn’t much better than hevc (h265), it’s just open and patent free and Google is pushing it like crazy.
It has iirc 1 major feature over hevc, non-square subpictures, beyond that it has some extensions for animation and slideshows basically.
